Definition
In music, si is the note name used in some systems for the pitch that English speakers usually call “B.” It appears in fixed-do solfège and in many Romance-language naming systems.
Usage & Nuances
This is a specialized music term, not a common everyday English word. In English-speaking contexts, learners will more often see “B” than “si”; use si mainly when talking about solfège, singing practice, or note names in other languages.
